In Italy, a tradition developed for re-enacting the birth of Christ and the construction of scenes of the nativity. This is said to have been introduced by Saint Francis as part of his efforts to bring spiritual knowledge to the laity.
Saints Days have also contributed to our Christmas celebrations. A prominent figure in today's Christmas is Saint Nicholas who for centuries has been honored on December 6th. He was one of the forerunners of Santa Claus.
Another popular ritual was the burning of the Yule Log, which is strongly embedded in the pagan worship of vegetation and fire, as well as being associated with magical and spiritual powers.
